It's worth taking a trip to the Illawarra Regional Airport in Albion Park this Sunday simply to see how organisers have managed to squeeze so many huge aircraft into the one small space.

It's not only that these planes represent a wide period of international and war time aviation, it's an exhibition of parking.

Old favourites will be there like the Constellation ('Connie'), Catalina, DC3 and DC4 airliners, as well as fast jets and warbirds, Routlettes and the Army Red Beret parachute team.

The annual event has become a popular tourist attraction for the South Coast, with CityRail putting on extra trains to Albion Park to accommodate the visitors.

"We find these beaut aeroplanes that if we don't get them they'll be wrecked so we say we'll have it and we deal with it after we get it," Historic Aircraft Restoration Society president Bob De La Hunty said.

"I always get up the stairs to the Connie and pinch myself that I get to fly this with its big wings and engines and all the famous people that in the 50s that came up these stairs."
